corrupt audio files PT 8.0.3

[Felix Rost]

I just had the same issue:
The session was fine before I closed.
I opened today and the 1 last recording file is reported offline. It is visible in finder and the workspace browser but can't be opened by any application.
The backup I did right after the recording is the same.

My client needs this file!

Mac OS 10.6.3
LE 8.0.3cs2

I managed to restore the file with SH header repair.

This is the worst Protools bug since dissappearing regions in 7.3!

(I know 10.6.3 is not yet qualified)

A friend of mine's got this problem.
Felix> How exactly did you do the header repair, is that some kind of software? Maybe you have a link?
thanks

Tim,
I used Soundhack for this, it's free.

Felix, hate to say it, but I'm pretty sure 8.0.3 has issues with missing regions as well.

good to know about the soundhack fix for these corrupt audio files.

I have been having similar problems, when inverting a file using the AudioSuite facility, that file can not be found on re-opening the session.

I know I could just invert in using one of the eq's or whatever but this shouldn't be a problem.

Could you test this using a different drive and let us know if the same problem occurs?

Just tested this with my system drive and with my external drive, both worked fine this time. As I said though, it seems to just randomly happen. Will it make a difference inverting it on LE and opening it the next time on HD? I think thats when I found out, when I inverted in on my LE and then took it to the HD in the studio. I'm not able to test this atm. Shouldn't be a problem though I wouldn't have thought.

I had the same problem a few weeks ago.
MacPro 8 core, OS X 10.6.3, PT 8.0.3cs2.

I was recording engineer for 2 days on this session, 20 composers for a seminar with a chamber orchestra. I was not the ProTools engineer so I don't know for sure if there were errors when recording but I suspect not. The person running ProTools was very good.

When I went to mix the sessions, 2 audio files were corrupted. Different sessions. They were in the Audio Files folder, and the Finder saw them but ProTools did not recognize them as audio files.

I suspected a header problem. I tried Soundhack and it would not fix the header.

I opened a hex editor and compared a couple of good tracks of that take against the corrupted track. I noticed the header was fine for the first few bytes until after the ProTools information, then went crazy until the 'data' section then seemed to be OK. I tried just copying the info from the good file to the bad, maintaining the sector count so the file length wouldn't change. It worked.

Now, I had 30 tracks that were recorded at the same time for each take so I could compare one file with another. If I had recorded only one track at a time I don't know if I would have found the header corruption. I haven't had any corrupted files since so I don't know what was going on - although, the studios I've been working at have older versions of PT, not 8.0.3.

I could see if I still have the corrupted files around to specifically detail what I fixed (if anyone is interested) but I suspect that they're gone. I think I fixed the problem and deleted the bad files.
I have mixed all the tracks from that session - on that machine with PT 8.0.3cs2 - and not one corrupted file.

I'm thinking it's a bad drive or bad drive format on the one you're having problems with.

If the problem doesn't occur with the drive you're currently using, I would recommend backing up the problematic drive, erase it and copy everything back, then test again.
